I have ask several people about this and still have no answer. I hope someone here can set us straight.
One of the first rules of electricity is (it follows the path of least resistance)
If this rule is right why does electricity run through the 15 OHM resistor when you have a charging system working properly but when voltage drops it travels through the light. Seems it should travel the same path both times.
Hope I am not being too ignorant.
Thanks
Paul

When the alternator is charging there is 12V coming from that direction also. With 12V on both sides and no ground the bulb can't light. | | |
